The Unix timestamp is designed to track time as a running total of seconds from the Unix Epoch on January 1st, 1970 at UTC. To add 24 hours to a Unix timestamp we can use any of these methods:
Method 1: Convert 24 hours to seconds and add the result to current Unix time.
- Program:
<?php
echo time() + (24*60*60);
?>
|
- Output:
1588671070
Method 2: Since hours in a day vary in systems such as Daylight saving time (DST) from exactly 24 hours in a day. It’s better to use PHP strtotime() Function to properly account for these anomalies. Using strtotime to parse current DateTime and one day to timestamp
- Program:
<?php
echo strtotime ( "now" ), "\n" ;
echo strtotime ( '+1 day' );
?>
|
- Output:
1588584696
1588671096
Method 3: Using DateTime class we can achieve same result. First create a DateTime object with current timestamp and add interval of one day. P1D represents a Period of 1 Day interval to be added.
- Program:
<?php
$now = new DateTime();
$now ->format( 'Y-m-d H:i:s' );
echo $now ->getTimestamp(), "\n" ;
$now ->add( new DateInterval( 'P1D' ));
echo $now ->getTimestamp();
?>
|
- Output:
1588584729
1588671129
